I'll start with your first question.
The animal by-products have to be rendered, or they have to be processed in some way first, and once they become the fats and oils that turn into biodiesel, they're quite easily transported. In fact, our company, before we got into biodiesel, exported them around the world to places such as South America. So they do transport very well.
The thing to remember, though, is that there's a finite supply of animal by-products, because they're by-products of what we eat. So it is a low-cost input for biodiesel at the moment, but there is a limited supply. We are going to need the oilseed crops and the soybean and the canola oils to make this industry big. There will be plants that will use both products very successfully, and there's technology in Canada that works very well for that. In fact, one of the plants is being built in Hamilton.
What we need to remember, though, is that eventually we will run out of animal by-products and animal fats, and it is going to be very important to have primary producers, like the canola and soybean producers, involved as well.
